you need to install glib-2.0 using this command (your command did regex on available packages):

sudo apt-get install libglib2.0-dev

[mdk73]

Thanks again for your support!

Yes, sudo -H apt-get install libglib2.0-dev did the trick, after that I could succesfully install pythonnet with sudo -H pip3 install pythonnet --pre -U.

Now I tried to run a script developed and working under Windows, and it failed.
A minimal working example:

print('import clr')
import clr
print('clr imported')

if __name__ == '__main__':
    print('main')
    exit(0)

gives the following traceback:

import clr

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

this answer suggests that some wrong C code is written either in pythonnet C API calls to Mono runtime or in the Mono runtime itself:

http://stackoverflow.com/a/23680335/2230844

I have no expertise to debug this, maybe you can send issue to bug tracker of Mono project.

[den-run-ai]

apparently there are known issues with mono support on raspberry + arm:

https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=11634

[mdk73]

A follow-up from my side: I tried to solve the issue with the help of the mono mailing list. Some test code was running with nPython.exe, but not with pythonnet (some library in the ubuntu system was still throwing an error...). I tried if it was possible to run my complete code with nPython.exe, that failed as I use additional libraries and drivers which could not be handled through nPython. I made an attempt to install a fresh Ubuntu in a VM ( so no arm-architecture, just normal PC), went again through all the steps of installing mono and pythonnet, but it still did not work... At that point I simply gave up wasting my time chasing errors I do not understand. A tiny windows PC is doing now its work, up and running smoothly in less than one evening... The price (with windows installed) is appr. 7 times higher than an raspberry, but at least I have now a working solution :-/. Maybe it safes someone else some time (though not money...).

Can you point to your troubleshooting on Mono mailing list for future reference? Please open a separate issue for Mono on desktop non-ARM Ubuntu (x86 or x64), because this is working and tested environment. We recommend using non-System Python such as Miniconda due to problems with shared libpython. Search this issue tracker for your possible errors.
